The Global Peace Index for 2022 has some interesting results. It apparently measures the most peaceful countries. I don't know how accurate it is, but it would be interesting to compare a few more of these rankings/surveys to see if there's a general consensus.

Some countries of interest to me were:
12. Canada
30. Taiwan
38. Costa Rica
46. Uruguay
55. Chile
69. Argentina
77. Paraguay
81. Dominican Republic
89. China
129. USA
130. Brazil
One thing I would like to ask, though, is about the Ecological Threat Report (another link on that same website). It gives Uruguay a 5 under Natural Disasters (you have to specifically select Uruguay on the Countries dropdown list). Is that an error on their part, or do they know something that I don't?
